Dear all:
The LDO has enough phase margin when no load or light or heavy load.
But if I use a pulse current such as
Iout vout 0 pulse( 0 2 800u 1n 1n 100u 200u)
the circuit will ring
And if
Iout vout 0 pulse( 10m 2 800u 1n 1n 100u 200u)
the circuit will be fine.
Why? setting Iout as a zero current when transient simulation is not resonable ?
Thanks for your answer.
